Embodiment Construction

[0077] In the present invention, a fixed predetermined dose of a secondary drug compound (secondary drug) and a variable dose of a primary or primary drug compound (primary drug) may be administered through a single output or drug dispense interface. User-set dosing of the primary drug may automatically determine a fixed dose of the secondary drug, preferably a single dose contained in a reservoir or cartridge with an integrated flow dispenser. In a preferred embodiment, the medicament dispense interface is a needle cannula (hollow needle). figure 1 Dosing Module 4 is shown (see figure 2 or 7) An example of a drug delivery device 7 connected. The medicated module 4 is connectable to connection means 9 provided on the cartridge holder 50 at the distal end 32 of the device 7 . Each medicated module 4 is preferably self-contained and provided as a sealed and sterile disposable module having engagement means 8 compatible with engagement means 9 on the distal end 32 of the devic...

Abstract

A medicated module (4) for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module (4) containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle (3). The medicated module (4) does not require the user to manually engage a reservoir (22) containing the secondary medicament. Instead, a biasing member (48) automatically activates the reservoir (22) when the needle guard (42) is retracted. The needle guard (42) prevents accidental needle sticks before and after an injection, and locks after dose delivery.

Description

technical field [0001] Particular embodiments of the present invention relate to medical devices and methods of delivering at least two medicaments using a device having only a single dose setting mechanism and a single dispense interface. A single delivery program initiated by the user may result in a non-user settable dose of the second or secondary drug and a variable set dose of the first or primary drug to be delivered to the patient. The medicament may fit into two or more reservoirs, containers or packs, each containing individual (single drug compound) or premixed (reconstituted multiple drug compounds) medicament. In particular, the present invention relates to a medicated module wherein the user does not have to manually select or program the module to dispense a second medicament. Activation of the needle guard may automatically cause the reservoir of the secondary medicament to engage the dispensing catheter to allow injection of a set dose of the primary medicame...
